Description

Technical Field

[0001] This utility model relates to the field of quick-detachable coating machine nozzles, and more particularly to quick-detachable coating machine nozzles. Background Technology

[0002] A coating machine is an industrial device that uniformly coats liquid or slurry-like materials onto the surface of a substrate (such as film, paper, metal foil, fabric, etc.). The coating process is a key step in many manufacturing processes, used to impart specific functionalities to materials, such as conductivity, insulation, adhesion, optical properties, or protection. The coating machine nozzle is a crucial component that directly and uniformly coats the coating material (slurry, liquid, or colloid) onto the substrate surface, determining the uniformity, thickness accuracy, edge control, surface quality, and production efficiency of the coating.

[0003] The prior art patent CN214416820U discloses a coating nozzle device for a coating machine, including a nozzle device and a mixing tank. A pump body is located near the bottom of the mixing tank, with one end connected to a delivery pipe and the other end connected to the nozzle device. The nozzle device includes a hollow metal tube with a first connecting part and a second connecting part at each end. The first connecting part is threaded to the delivery pipe, and the second connecting part is threaded to the nozzle. A heating sleeve is annularly fitted around the outside of the metal tube, and a first heating wire is located inside the heating sleeve. This invention uses the heating sleeve to heat the nozzle device and the heating wire to heat the delivery pipe, preventing hot melt adhesive from clogging the pipeline. It has a simple structure and good practicality.

[0004] However, existing coating machine nozzles require cleaning after prolonged use. But because they are installed on the coating machine, they cannot effectively clean every nook and cranny. Also, after long-term use, the nozzles need to be maintained, which requires disassembly. However, existing nozzles require tools for disassembly, and the disassembly process is relatively complicated and inconvenient, affecting subsequent work efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick-disassembly coating machine nozzle with a convenient disassembly and assembly structure, which facilitates subsequent maintenance. It solves the problems of existing coating machine nozzles having a relatively complex disassembly and assembly process, requiring tools, being time-consuming and labor-intensive, and inconvenient for subsequent maintenance.

[0006] The technical solution of this utility model is as follows: a quick-detachable coating machine nozzle, including a spraying frame, a positioning block provided on the lower end face of the spraying frame, a mounting base provided on the upper end face of the spraying frame, a slot provided inside the mounting base, a first through hole provided at both the upper and lower ends of the mounting base, a sliding groove provided at one end of the first through hole, a second through hole provided at one end of the sliding groove, and plug-in components provided on both the left and right sides of the second through hole. A nozzle body is provided inside the mounting base, a limiting groove is provided on both the upper and lower end surfaces of the nozzle body, a sliding groove is provided on both the left and right sides of the limiting groove, a first fixing groove is provided at one end of the limiting groove, a second fixing groove is provided at one end of the first fixing groove, a movable block is provided inside the limiting groove, guide members located inside the two sliding grooves are fixedly connected to both the left and right sides of the movable block, a fixing block is fixedly connected to the upper end face of the movable block, and plug holes are provided on both the left and right sides of the fixing block. An elastic member located inside the two sliding grooves is connected to one end of the two guide members. A reinforcing member is sleeved between the nozzle body and the mounting base.

[0007] Furthermore, the guide component includes guide blocks, both of which are slidably located within two sliding grooves. While the movable block slides within the sliding grooves, the two guide blocks assist in sliding within the two sliding grooves.

[0008] Furthermore, the elastic element includes a first spring, which is located at one end of the two guide blocks and within the two sliding grooves. While the movable block slides within the limiting groove, it is stretched and contracted by the elastic action of the first spring.

[0009] Furthermore, by inserting the plug into the slot, and at this time inserting the movable block into the second fixed slot, and making the fixed block and the mounting base pass through the first through hole, the movable block is disengaged from the second fixed slot, allowing the movable block to slide in the slide groove, and finally the movable block is inserted into the first fixed slot, so that the fixed block is engaged in the second through hole.

[0010] Furthermore, the plug-in assembly includes plug rods, with a second spring sleeved on the outside of the plug rods. When the plug rods are inserted into the second through hole by the fixing block, the two plug rods and the second spring are simultaneously pressed to one side, so that the two plug rods are inserted into the two plug holes for fixing between the nozzle body and the mounting base.

[0011] Furthermore, the reinforcement includes a reinforcing collar, the inner wall of which is provided with external threads, and the outer walls of the nozzle body and the mounting base are provided with internal thread grooves. The reinforcing collar is engaged with the outside of the nozzle body and the mounting base to reinforce the fixation between the nozzle body and the mounting base.

[0012] Furthermore, the positioning block has a positioning groove inside, through which the nozzle body and the positioning block pass and are inserted into the slot inside the mounting base for positioning the nozzle and the mounting base.

[0013] The beneficial effects of this utility model are: This quick-detachable coating machine nozzle offers advantages such as easy assembly and disassembly without tools, significantly improving maintenance efficiency and saving time and manpower. Precise positioning is achieved through a positioning block, while the guide block and sliding groove ensure smooth sliding. The insertion rod and spring structure enable quick locking and release, resulting in a stable connection and fast operation. The added reinforcing collar further enhances the stability and sealing of the connection. The overall structural design is reasonable, effectively solving the problems of complex, time-consuming, and labor-intensive assembly and disassembly of traditional nozzles, facilitating daily maintenance and replacement.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5The quick-detachable coating machine nozzle in this embodiment includes a spray frame 1. A positioning block 3 is provided on the lower end face of the spray frame 1, and a mounting base 5 is provided on the upper end face of the spray frame 1. A slot 6 is provided inside the mounting base 5. First through holes 13 are provided at both the upper and lower ends of the mounting base 5. A sliding groove 14 is provided at one end of the first through hole 13, and a second through hole 15 is provided at one end of the sliding groove 14. Insertion components are provided on both the left and right sides of the second through hole 15. A nozzle body 2 is provided inside the mounting base 5. Limiting grooves 18 are provided on both the upper and lower surfaces of the nozzle body 2. Sliding grooves 19 are provided on both the left and right sides of the limiting grooves 18. A sliding groove 19 is provided at one end of the limiting groove 18. The first fixed groove 20 has a second fixed groove 21 at one end. The limiting groove 18 has a movable block 12 inside (the sliding path of the movable block 12 is defined by the sliding groove 14 and the limiting groove 18, and the two correspond precisely in space to ensure that the movable block does not deviate or get stuck during the sliding process). The left and right sides of the movable block 12 are fixedly connected to guide members located inside the two sliding grooves 19. The upper end face of the movable block 12 is fixedly connected to a fixed block 8. The left and right sides of the fixed block 8 are provided with insertion holes 10. One end of the two guide members is connected to an elastic member located inside the two sliding grooves 19. The nozzle body 2 and the mounting base 5 are externally sleeved with a reinforcing member.

[0018] In this embodiment, precise positioning is achieved through positioning block 3, smooth sliding is ensured by guide block 11 and sliding groove 19, and quick locking and releasing is achieved by insert rod 16 and second spring 17. The connection is stable and the operation is quick. The added reinforcing collar 4 further enhances the stability and sealing of the connection. The overall structure is reasonably designed, which effectively solves the problems of complicated disassembly and assembly, time and labor cost of traditional nozzle body 2, and facilitates daily maintenance and replacement.

[0019] Please see Figures 2-5In this embodiment, the guide component includes guide blocks 11, both of which are slidably located within two sliding grooves 19. While the movable block 12 slides within the sliding groove 14, the two guide blocks 11 assist in sliding within the two sliding grooves 19. The elastic component includes a first spring 9, located at one end of each of the two guide blocks 11 and within the two sliding grooves 19. While the movable block 12 slides within the limiting groove 18, the first spring 9 (a fatigue-resistant, small-sized compression spring is selected, and its elastic coefficient is calculated to match the sliding stroke of the movable block, ensuring stable elastic force output during repeated disassembly and assembly, preventing insecure locking due to spring failure) stretches and contracts under its elastic action. This allows the plug 7 to be inserted into... The movable block 12 is inserted into the second fixed groove 21, and the fixed block 8 and the mounting base 5 pass through the first through hole 13. The movable block 12 is disengaged from the second fixed groove 21 and slides in the slide groove 14. Finally, the movable block 12 is inserted into the first fixed groove 20, so that the fixed block 8 can be inserted into the second through hole 15. The plug-in assembly includes a plug rod 16. The plug rod 16 (the end of the plug rod 16 is also provided with a 45° guide slope) is sleeved with a second spring 17. When the fixed block 8 is inserted into the second through hole 15, the two plug rods 16 and the second spring 17 are pressed to one side synchronously, so that the two plug rods 16 are inserted into the two plug holes 10 for fixing between the nozzle body 2 and the mounting base 5.

[0020] It should be noted that, firstly, the nozzle body 2 is aligned with the positioning groove of the positioning block 3 and inserted into the slot 6 of the mounting base 5 to achieve initial positioning and axial limiting; at this time, the movable block 12 is located in the second fixed groove 21. As the nozzle body 2 continues to be inserted, the movable block 12 slides along the sliding groove 14 and disengages from the second fixed groove 21 after being subjected to force. During this process, the guide block 11 slides synchronously in the sliding groove 19, and the first spring 9 is compressed and stores energy; when the nozzle body 2 is fully in place, the movable block 12 automatically slides into the first fixed groove 20 under the elastic restoring force of the first spring 9, driving the fixed block to move synchronously and lock into the second through hole 15. At this time, the insertion holes 10 on both sides of the fixed 8 are aligned with the second through hole 15, and the insertion rods 16 in the two-sided insertion assembly spring back inward under the elastic force of the second spring 17 and are inserted into the insertion holes 10 to achieve mechanical self-locking and complete the quick connection.

[0021] Please see Figure 1In this embodiment, the reinforcement includes a reinforcing collar 4, the inner wall of which is provided with external threads, and the outer walls of the nozzle body 2 and the mounting base 5 are provided with internal thread grooves. The reinforcing collar 4 is engaged and sleeved on the outside of the nozzle body 2 and the mounting base 5 to reinforce the fixation between the nozzle body 2 and the mounting base 5. The positioning block 3 has a positioning groove inside, and the nozzle body 2 and the positioning block 3 pass through the positioning groove and are inserted into the slot 6 inside the mounting base 5 for positioning of the nozzle body 2 and the mounting base 5.

[0022] It should be noted that the reinforcing collar 4 is screwed onto the outside of the nozzle body 2 and the mounting base 5 by threads, which not only improves the overall rigidity and shock resistance of the connection structure, but also effectively prevents loosening caused by medium pressure fluctuations or external vibrations during the coating process, while enhancing the sealing effect and preventing leakage.

[0023] The working principle of the above embodiments is as follows: In use, the nozzle body 2 is inserted into the slot 6 inside the mounting base 5 by inserting the plug 7 at one end of the nozzle body 2, and the positioning block 3 is used to ensure that the nozzle body 2 is correctly aligned, thus achieving initial positioning. After the nozzle body 2 is fully inserted, the fixing block 8 passes through the first through hole 13 and slowly slides in the slide groove 14 and is locked into the second through hole 15. During this process, the two insert rods 16 and the second spring 17 are synchronously squeezed and moved to one side until the insert rods 16 can be inserted into the insert holes 10 inside the fixing block 8, thereby achieving a stable connection between the nozzle body 2 and the mounting base 5. To further strengthen this connection, a reinforcing collar 4 is sleeved on the outside, and the inner wall of the reinforcing collar 4 is provided with an outer... The threads match the internal thread grooves on the outer walls of the nozzle body 2 and the mounting base 5. By rotating the reinforcing collar 4, it engages with the outside of the nozzle body 2 and the mounting base 5 to enhance the stability of the overall structure. When disassembly is required, the above steps are reversed. First, the reinforcing collar 4 is loosened, and then the fixing block 8 is pulled. Under the action of the pulling force, the insertion rod 16 is released, so that the insertion rod 16 is disengaged from the insertion hole 10. The movable block 12 can slide freely in the sliding groove 14 and disengage from the first fixing groove 20 or the second fixing groove 21. Thus, the nozzle body 2 can be easily removed from the mounting base 5. The whole process does not require the assistance of tools, achieving the purpose of quick disassembly and assembly, and greatly improving maintenance efficiency.
